I noticed the same problem since I installed 2.7.3 Pro. Lots of hits, but only 1 dozen or less uploads after being on for 3 or 4 hours. Sounds like a bug in their program to me. I haven't changed anything, so I dont need someone telling me to fix an IP address, as I wouldn't know how to do this anyway. I've also noticed that I don't get quite as many multiple hosts on common files as I used to either. Are we narrowing the field of exposure here to streamline the network??
